Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504144, here are decompositions:

11 + 31504133 = 31504144
17 + 31504127 = 31504144
41 + 31504103 = 31504144
47 + 31504097 = 31504144
107 + 31504037 = 31504144
131 + 31504013 = 31504144
167 + 31503977 = 31504144
173 + 31503971 = 31504144

Showing the first eight; more decompositions exist.
